> I have been in contact with both the Marketing and Legal Departments at Keysight Technologies and have been assured that this webinar is available to the general public and to anyone who is interested in watching it. I found it to be an excellent source of information with pictures, graphics and movies that presents the fundamentals of Network Analysis is five parts: (1) What is a Network Analyzer, (2) Transmission Lines and S-Parameters, (3) Network Analyzer Block Diagram, (4) Network Analysis Measurements and (5) Calibration and Error Correction. Even though these topics are presented for the Keysight line of Network Analyzers, these are the basics and fundamentals and they apply to ANY Network Analyzer.
> After the webinar, don't forget to visit the "resources" listed in the Resource Box. There you can download the webinar slides, visit a marvelous webpage on "Keysight Network Analysis" and obtain a download of an application note (16 page PDF) that covers all the topics in this webinar and then some. It is an excellent document to start your Network Analysis Reference Library.
